Prerequisites

GRemoteActionGroup requires GActionGroup and GObject.

Known Implementations

GRemoteActionGroup is implemented by GDBusActionGroup.

Includes

#include <gio/gio.h>

Description

The GRemoteActionGroup interface is implemented by GActionGroup instances that either transmit action invocations to other processes or receive action invocations in the local process from other processes.

The interface has _full variants of the two methods on GActionGroup used to activate actions: g_action_group_activate_action() and g_action_group_change_action_state(). These variants allow a "platform data" GVariant to be specified: a dictionary providing context for the action invocation (for example: timestamps, startup notification IDs, etc).

GDBusActionGroup implements GRemoteActionGroup. This provides a mechanism to send platform data for action invocations over D-Bus.

Additionally, g_dbus_connection_export_action_group() will check if the exported GActionGroup implements GRemoteActionGroup and use the _full variants of the calls if available. This provides a mechanism by which to receive platform data for action invocations that arrive by way of D-Bus.

Functions

g_remote_action_group_activate_action_full ()

void
g_remote_action_group_activate_action_full
                               (GRemoteActionGroup *remote,
                                const gchar *action_name,
                                GVariant *parameter,
                                GVariant *platform_data);

Activates the remote action.

This is the same as g_action_group_activate_action() except that it allows for provision of "platform data" to be sent along with the activation request. This typically contains details such as the user interaction timestamp or startup notification information.

platform_data must be non-NULL and must have the type G_VARIANT_TYPE_VARDICT. If it is floating, it will be consumed.

Parameters

remote	a GDBusActionGroup
action_name	the name of the action to activate
parameter	the optional parameter to the activation.	[allow-none]
platform_data	the platform data to send

g_remote_action_group_change_action_state_full ()

void
g_remote_action_group_change_action_state_full
                               (GRemoteActionGroup *remote,
                                const gchar *action_name,
                                GVariant *value,
                                GVariant *platform_data);

Changes the state of a remote action.

This is the same as g_action_group_change_action_state() except that it allows for provision of "platform data" to be sent along with the state change request. This typically contains details such as the user interaction timestamp or startup notification information.

platform_data must be non-NULL and must have the type G_VARIANT_TYPE_VARDICT. If it is floating, it will be consumed.

Parameters

remote	a GRemoteActionGroup
action_name	the name of the action to change the state of
value	the new requested value for the state
platform_data	the platform data to send

Since 2.32

Types and Values

GRemoteActionGroup

typedef struct _GRemoteActionGroup GRemoteActionGroup;

GRemoteActionGroup is an opaque data structure and can only be accessed using the following functions.

struct GRemoteActionGroupInterface

struct GRemoteActionGroupInterface {
  GTypeInterface g_iface;

  void (* activate_action_full)     (GRemoteActionGroup *remote,
                                     const gchar        *action_name,
                                     GVariant           *parameter,
                                     GVariant           *platform_data);

  void (* change_action_state_full) (GRemoteActionGroup *remote,
                                     const gchar        *action_name,
                                     GVariant           *value,
